This is straight off my MSWord brainstorm(meaning some things might not make sense):

• An item that makes you enter an unknown world
• Multiple exploration logs
• It is in the real, physical world (so the item is kind of a teleporter, but not really).
• Subject using the item will remain in a trance state where they contacted the item, but will be conscious on the other world
• Subjects will have a compulsion to explore the world
• There are multiple similarities in the world for each person, but it is still, in a way, different.
• Ideas for the item; Soda can (that one’s been in my mind for some reason.), a sculpture of some other worldly animal, a piece of artwork depicting the world,

What the world looks like (Here we go, everyone):
• Generally has a green/blue tint in its environment.
• Partially foggy
• Plant life and animal life is switched (humans rooted to the ground, plants walking around communicating)
• Some hills, other than that, mainly flat
• A ‘forest’ of humans, or other animals
• The grass is some sort of small insect (ants, flies, possibly spiders)

I think you're trying to capture the feel of SCPs like SCP-087, SCP-093, SCP-167, SCP-201, SCP-432, and SCP-648. I think it's a laudable goal because I love SCPs like that, but I think you'll have a damned hard time trying to squeeze into an already over-saturated space and that you'd be better off exploring something else.
